The TV mogul welcomed his first child Eric in February, with girlfriend Lauren Silverman, but it seems he already wants to add to his brood.

Westlife's Kian was quoted as telling the Daily Star Sunday: "Simon seemed pretty excited and he told me he wanted to have another child fast. I told him to give his missus time to recover first."

"The thing about Simon is, it's all come as a surprise. Even when he got his dogs he didn't realise how much he would love them. I told him to wait until he has a baby and wait until that baby starts having its own personality then he's in a different place all together," added Kian, who has a son named Koa.

After welcoming Eric on Valentine's Day, 54-year-old Simon said he was "born to be a dad".

The X Factor star also told US TV show Extra that he'd like a brother or sister for his son.

"I wouldn't rule out [more children]. Well, I got (Yorkshire terriers) Squiddly and Diddly, and I couldn't imagine Squiddly or just Diddly... I had a brother when I was younger, so I kind of think it's cool to have two or three... two," he said.
